Since ES5, it is possible to create objects with no prototype at all: let foo = Object.create(null); Those object won't have any builtin properties like hasOwnProperty(), which is why eslint added a corresponding rule to its default rule set. While this isn't an issue that affects our code, there's no harm in fol- lowing the recommendation and call the method through Object.prototype. https://gitlab.gnome.org/GNOME/gnome-shell/merge_requests/716
